I have used the GLSL in maya by developing my own shader plugins.
I used the Colladafx and it is really good, because it is having support for multiple passes, but it only support CG and CGFX files.
Is there any way that i can use GLSL with Colladafx?
Feeling Software is releasing the source code of the plug-ins primarily so others like you can contribute and adapt it to your specific needs. We are always happy to test and merge external contributions in the official branch. It would be fantastic if you could help us integrate GLSL support in the COLLADA FX plug-in. Let me know if you have the time to do so, in which case we should continue the discussion offline and we’ll provide help wherever possible.
